About Arctic grayling
The sail-finned salmonid of the far north — instantly known by its huge, iridescent dorsal fin. A staple of Alaska’s clear interior rivers and lakes (and a relict in a few Montana and Wyoming waters), it rises eagerly to dry flies in cold, fast water through the brief subarctic summer. Lightly pressured and abundant where it occurs.
Thymallus arcticus, family Salmonidae.
